And when Saul marched out with his army, he warned: "Allah is going to put you to a test by the side of a river: whoso drinks of its water shall cease to be my companion: he alone shall be~my companion who does not quench his thirst with its water: one may, however, take except a few, drank their fill of it. Afterwards when Saul, and those who had believed with him, crossed the river and advanced forward, the former said to Saul, "We have no power left this day to fight against Goliath and his hosts." But those who believed that one Day they shall meet Allah, declared, "lt has often been that a small host has, by Allah's grace, overcome a big host: for Allah is with those who show fortitude." 249 And when they went forth to [face] Goliath and his soldiers, they said, "Our Lord, pour upon us patience and plant firmly our feet and give us victory over the disbelieving people." 250 They defeated their enemy through God's will. David slew Goliath and God granted David the kingdom and wisdom and also taught him whatever He wanted. Had God not made one group of people repel the other, the earth would have become full of corruption, but God is generous to His creatures. 251 These are the verses of Allah. We recite (them) to you in truth, for you (Prophet Muhammad) are one of the Messengers. 252 ۞ Of these Messengers, We have preferred some above others. To some Allah spoke; and some He raised in rank. We gave (Prophet) Jesus, the son of Mary, clear signs and strengthened him with the Spirit of Purity (Gabriel). Had Allah willed, those who succeeded them would not have fought against one another after the clear verses came to them. But they differed among themselves; some believed, and others disbelieved. Yet had Allah willed, they would not have fought against one another. Allah does whatever He will. 253
